The cost of an office fit-out predominantly depends on 4 factors:
- Office square footage (also known as office footprint)
- Extent of fit-out (please note, other than the per sqft reference, this table would be irrelevant if there are only minor alterations required in an existing space)
- The current office condition
- Specification

| Per sqft | £50 – £80 | £75 – £110 | £105 – £135 |

How much does an office fit-out cost per square foot in London?
The average cost per sqft for a London-based office fit-out or refurbishment varies from £50 – £140. Where your project is priced depends on various factors, such as whether the fit-out should be low, mid, or high spec. Other considerations are:
Current office condition
The current condition of your office is the first thing you’ll need to consider when looking to refurbish your office. If you’re moving into a new office, you’ll want to note the condition of the existing landlord’s systems and finishes (HVAC, ceilings, floor and wall finishes, lighting, electrical).
Construction
Construction is by far the most labour-intensive part of the process. If your project requires a great deal of work, you will need to account for labour costs. This might include the installation of new glass or plasterboard partitions for example.
Furnishings
Furniture is considered a cosmetic alteration, and costs are dependent on your chosen aesthetic. If your office has existing furniture that would function in the improved office environment, we try to reuse where possible to reduce both the cost and the environmental impact.
Mechanical, Electrical, and AV
Whilst mechanical needs include standard systems such as heating, air conditioning, and elevator improvements, electrical and AV needs depend more on your business requirements and existing systems in place. For example, if your business practices hybrid working, your space will likely need meeting rooms that enable virtual participation in meetings.
Design
This is something you should be wary of when considering your office fit-out. At Aster, we offer a complimentary design service, tailored to your requirements and budget aspirations. This office design is no-obligation and can be used to give an accurate cost per square foot before the project commences.
Timeframe
It’s important to note that the urgency of your project will have an impact on cost. A fast turnaround will require more work out of hours or weekends, in a shorter time frame.
